A kid who thinks he is funny by saying things but really isn't. This type of person generally fails at life, has no friends and sits at their computer all day long. These people are different from trolls in the sense that they fail at trolling too and have no actual value to contribute to society or life.

A fail kid is someone who stalks you on facebook, posts random fail comments and thinks hes cool and good at everything they do.
